Exercise device



FIG. 1 is a perspective view of an exercise device, showing my new design;

FIG. 2 is a right-side elevational view thereof, the left-side elevational view being a mirror image thereof;

FIG. 3 is a top plan view thereof;

FIG. 4 is a front elevational view thereof;

FIG. 5 is a rear elevational view thereof; and,

FIG. 6 is a bottom plan view thereof.

The broken lines showing a pair of exercise accessories in FIG. 1 depict environmental matter, and form no part of the claimed design. 

I claim the ornamental design for an exercise device, as shown and described.
